Questions about Logic Board

[FireStealer]

Hi everyone!

I'm a lifelong PC user who is finally making the transition to Mac. My mom and I just ordered a 15" MacBook Pro as a Bday/Christmas present and I'm really excited!

Anyway, my question is, what exactly is the logic board and why/when does it have problems? I have two friends who each have a MBP (both around 2.5 years old) and they've both needed to have the logic board replaced. It sounds like a scary experience, opening your comp and seeing that it just doesn't work, so is there any way to prevent this sort of thing from happening?

I haven't been able to find much info on this topic, so sorry if this is a repost. I'm trying to get as much info as possible on how to make my MBP last a while. Thanks a lot!

The logic board is the thing inside the computer that virtually everything is connected to, the CPU and GPU is attached to it and your hard drive, optical drive, USB/firewire ports - absolutely everything - is connected to it in some way. If you're coming from a PC then you're probably more familiar with the other name used for it - the mother board.

Because of what it is and how it works you can't do anything to 'stop' it from failing or do anything to 'prevent' it from failing - it is pretty much the central nervous system of your computer, it connects everything to everything else.
